Claims.

to produce in standard or any other desired size,

as often as needed, the different colors of vari ously colored objects by means of direct photography.

While formerly this was done in a "one or in a three in one camera, a plurality of colors of objects may be reproduced with this device.

Another object is to provide a frame into which dry, wet, or emulsion plates of standard or other size may be fitted to permit perfect register of any number of exposed color plates. Another object is to provide a frame having adjustable side members whereby to accommodate various sizes of plates.

With these and other objects in view the invention will be better understood by referring to the following specification and accompanying drawings wherein like numerals represent corresponding parts and Fig. 1 is an elevational view of the device with a color plate clamped in position and partly broken away.

Fig. 2 is a section taken on the line 22,of Fig. 1.

Fig. 3 is an enlarged detail view taken on the line 3-3 of Fig. 1.

Fig. 4 is a modified detail of the frame construction.

Fig. 5 is a section taken on the line 5-5 of Fig. 4. T a

, Fig. 6 is a plan view of a register mark for offset or rotogravure printing positive.

Fig. '7 is a plan view of a register mark for photoengraving or typaprinting.

Fig. 8 is a plan view of a register mark for offset or rotogravure printing negative.

Fig. 9 '.s an ele'vational view of a modified form of frame.

Fig. 10 is a rail of Fig. 9.

Fig. 11 is an enlarged section taken on the line IIII of Fig. 9, and

Fig. 12 is a perspective view of one of the upright members of Fig. 9.

Referring more particularly to Figs. 1 to 8 inclusive, I indicates a rectangular frame having a top wall), bottom wall 3 and side walls 4 and 5 respectively. Arranged on the outer periph- 5 cry of the walls 2 to 5 inclusive in close proximity top plan of a position of the top to the front face 6 of the frame I is a rib I having sets of saw like teeth 9 arranged longitudinally thereon adjacent the corners I0 thereof. The teeth 9 are adapted to hold the frame I in immovable position in a camera during the loading and exposing of the sensitized material. Arranged on the inner face of the walls 3 and 4 in close proximity to their ends are wedge-shaped blocks II.

Slots I2 are formed in the inner edges I3 of the frame I adjacent the corners I4. thereof. Lugs or nail heads I5 are formed on the inner faces of the side walls I6 of the frame I in close proximity to the ends thereof.

Formed in the mid-portion of the walls I6 and spaced from the inner face of the walls 4 and 5 are transverse slots I'I.

Formed in the mid-portion of the walls I8 and I9 of the frame I intermediate the ends of the walls 2 and 3 are cross-like slots 20.

The nail heads I5 are adapted to prevent close contact of the wet-plate material 2I' with the frame I to eliminate damaging the skin thereof.

A plurality of hook-like spring clamps 22 are adapted to hook over the walls 2, 3, 4, and 5 with one end 23 in engagement with the wet-plate 2| whereby to prevent the plate from back sliding. The edges 24 of the wet plate 2| are adapted to engage the inner edges 26 of the wedges II which in turn serve to prevent back sliding of the wet plate 2|.

The slots I1 and 20 are standard register marks. In Figs. 4 and 5 is shown a modification of the frame I wherein the wall IBa is provided with a rectangular slot I8 extending inwardly from the edge I8b thereof. The edges I80 are of dove tail formation as clearly shown in Fig. 5, the inner wall I8d of the slot being provided with an opening I 8e. A plurality of register blocks 21 are adapted to be removably mounted in the slots I8, the plate 21a having longitudinal slots 28 arranged in step formation this indication being used in photo-engraving. In Fig. 6 the block 21b is provided with a cross-shaped slot 29, this indication being used for negative on exposed material. In Fig. 8 block 210 is provided with a slot 30 whereby to provide a cross-like rib 3| and used as an indication for positive on ex posed material.

Either or all of the blocks 21 may be used for offset reproduction or for rotogravure reproduction -it being unnecessary to change the indications II.

The slots I2 are used as negative corner marks, and positive on exposed material. The

slots 2 facilitate uniform ruling and opaqueing on exposed plates, eliminating blur of the-colored picture.

In Figs. 9 to 12 inclusive is shown a modified form of frame 32, which consists of an L shaped top rail 33 and bottom rail 34. The rails 33 and 34 are provided with a plurality of slots 35 arranged in predetermined position on the horizontal legs 33 and 31 thereof respectively.

Upright rails 38 and 39 of L shaped formation are provided with legs 40 and 4| respectively. The legs 40 and 4i are provided with lugs 4ia projecting outwardly from the ends thereof:

which are adapted to be arranged-in certain of the slots 35 for various size plates. 4

The legs 40 and 31 are provided with wedg shaped lugs 42. The legs 43 and 55 of the rails 33 and 33 respectively are provided with register marks 45 and legs 33 and 34 are provided with register marks 46, and are cut off as at 41 to abut the edges of legs 33 and 34, as clearly shown in Figs. 9 and 10. Nail heads 48 are provided on the legs 43 and 44.

From the foregoing it will be seen that any number of plates may be exposed according to the number of colors desired and all plateswill have the same register marks fitting perfectly with each other. 1

When it is desired to add lettering to direct color photography with the' aid of the device, type in white or color can be added to the negaing relatively narrow front wall on said frame,

laws of saw-tooth formation formed on said rib extending laterally therefrom adjacent the corners thereof, and wedge blocks formed on the inner face of one side and bottom wall of said frame in close proximity to the ends thereof, said blocks having outwardly tapered front ends terminating adjacent said front wall, said front wall having register slots formed intermediate the ends thereof.

2. A device of the class described, including in combination a rectangular frame, a rectangular rib extending entirely around said frame adjacent the front edge thereof, an inwardly extending relatively narrow front wall on said frame, jaws of saw-tooth formation formed on said rib extending laterally therefrom adjacent the corners thereof, wedge blocks formed on the inner face of one side and bottom wall of said frame in close proximity to the ends thereof, said blocks having outwardly tapered front ends terminating adjacent said front wall, said front wall having rectangular slots extending inwardly from the edges thereof, tapered side walls formed. in said slots, and perforated register blocks having tapered sides mounted in said slots.

3. A device of the, class described, including in combination, a rectangular frame, a rectangular rib extending entirely around said frame adjacent the front edge thereof, jaws of saw tooth formation formed on said rib extending laterally therefrom adjacent the corners thereof, an inwardly extending relatively narrow front wall on said frame said front wall having rectangular slots extending inwardly from the edges thereof, tapered side walls formed in said slots, and perforated register blocks having tapered sides mounted in said slots.

4. A device of the class described, including in combination, a rectangular frame, a rectangular rib extending entirely around said frame adjacent the front edge thereof, jaws of saw tooth formation formed on said rib extending laterally therefrom adjacent the corners thereof, an inwardly extending relatively narrow front wall on said frame said front wall having rectangular slots extending inwardly from the inner edges thereof, tapered side walls formed in said slots, perforated register blocks having tapered sides mounted in said slots, and means for clamping a wet plate to said front wall.

5. A device of the class described, including in combination, a rectangular frame, a rectangular ribextending entirely around said frame adjacent the front edge thereof, an inwardly extending relatively narrow front wall on said frame, Jaws of saw-tooth formation formed on said rib extending laterally therefrom adjacent the corners thereof, wedge blocks formed on the inner face of one side and bottom wall of said frame in close proximity to the ends thereof, said blocks having outwardly tapered front ends terminating adjacent said front wall, said front wall having rectangular slots extending inwardly from the inner edges thereof, tapered side walls formed in said slots, and perforated register blocks having tapered sides mounted in said slots, said frame having end walls adjustably mounted in the top and bottom walls thereof.
